5w-40 valvoline synpower is the only synthetic (besides VW Dealer supplied oil) that has VW approval...says so on the bottle if you have a NAPA they can get it for you....i use it year round......
Valvoline SynPower 5w40 is perfectly fine for 10,000 change intervals. As long as it meats CI-4 or VW505.00 or ACEA B3, it's a perfectly ok oil.
Definitly noticed a difference from dino to synth, through research redline seems to be one of the best....so thats what i use
I too have used the SynPower since 16,000 miles. The tested sample had 8100 miles on it and had very good readings. I also had the Total Base Number tested which is the additive package. It was 2.0 which is low. They suggested I go no longer than 8100 miles on this oil in my engine due to the additives being low.
I ran this fill from mid Fall through the winter until 4/14/03. I filled up with about .25 of a qt 3000 miles into the interval. Analysis done by Blackstone Laboratories. Total miles on oil: 4,886 DAVID: Although we expect an engine’s break-in period to be past by about 10,000 miles, we suspect that the 5 ppm lead we found in this sample is from lingering wear-in. Upper-end wear (see aluminum, chrome, and iron) looks great. Lead should decrease in the next sample, as should silicon, which is leftover sealers used at the factory. Insolubles were good at 0.4%, showing your oil filtration system is getting the job done.
you can buy Valvoline Synpower at any NAPA Auto Parts Store.
Just go out and buy Valvoline SynPower 5W40...
I am the person who posted those Valvoline 5w-40 vs. Mobil 1 10w-30 results long ago and started spreading the word about this oil and where to find it. The results show that the Vavloline 5w-40 is a very good choice for this motor. The last sample had nearly 9,000 miles on it, and the oil was well within viscosity and oxydation tolerances for 5w-40, and labeled suitable for continued use. Further, after 9,000 miles, wear metals were very low.
Wear values perfect ! Looks like Redline is lowering the Moly value some . Your nox is normal but new plugs or wires could help lower the values, Oxd is elevated by cleaning effect of the POE base and lab equipment hates Redline, no problems though. Second change on this oil will drop OXD values. As I said before I have not seen this formulation before but it looks ROCK solid. Good TBN retention.
Valvoline Synpower also meets as many specs as Syntec. Synpower 5w-40 meets API SL/SJ, ACEA A3, and VW 502.00 and VW 505.00. Plus, you can get it for less than 5 bucks a quart
